The mum-of-two has hit back, claiming that the fallen First World War soldiers would have approved.

The Top 20 charting singer, from Loughborough, said: "'Pretty sure those boys that gave their lives for this country would enjoy a casual bit of side-boob."

Taken inside the grounds of a London church, the vocalist, who once sang for the Queen, at the official launch of the BBC's Broadcasting House in 2013, claims she was unaware that the plaque was a war memorial.

"Me and my best mate Jonjo were being creative in Clapham and saw the church and he was like 'go topless'. That’s it really. It’s not that deep," said the chart star, who has just released a new album, Not Girlfriend Material.
